Both the HTC Titan II and the Nokia Lumia 900 were released this week on AT&T. Both have many similarities as well. You’ve got high speed AT&T LTE data connections, Windows Phone 7.5, non-removable batteries, large screen sizes, 480×800 pixel screen resolutions, front facing cameras, 16Gb of storage, 512Mb of RAM and Qualcomm Snapdragon processors. But how do they differ and is that worth the price?

The Titan II has a slightly faster 1.5Ghz processor versus the Lumia 900’s 1.4Ghz processor and this shows in the benchmarks and HTML5 speed tests, however everywhere else it’s not noticable. Another difference in these two devices is the camera. The HTC Titan II has a 16 megapixel camera with dual LED flash, while the Nokia Lumia 900 has an 8 megapixel camera with dual LED flash. Both cameras launch at about the same speed and take single pictures at about the same speed, but the HTC Titan II has many more settings and options built into the camera software where as the Lumia 900 has a “Creative Studio” app that you can download separately for post-processing corrections and silly filter effects.

In the above 100% crop of two sample photos, we see the HTC Titan II’s photo on the left and the Nokia Lumia 900 on the right. It looks like the Titan II got much better color reproduction in this shot, however you can see a lot more noise where the Lumia 900 gets a bit smoother continous tones.

Value-added software differs between the HTC device and Nokia device as well. With Nokia you get “Drive” for free turn-by-turn navigation with free offline map data from all around the world. HTC’s “Locations” equivalent has a few more features than Nokia Drive, but its offline map data only includes a free 30 day trial. If you want to use offline map data after that it will cost a fee which varies depending on which maps you want and how long you want them for. Check out the video above for more details on exactly which free apps you get from each manufacturer.

Lastly, there’s the price difference. The Nokia Lumia 900 is available from AT&T for only $99 with a 2 year contract where as the HTC Titan II is priced at $199 for the same contract.

Technically, in many aspects, the Titan II is a better phone, but whether it’s worth the extra money is up to you.
